What is a DOP/PAO Test?
DOP/PAO testing is a very quick process that tests the integrity of the HEPA (High Efficiency Particulate Air) filter using DOP or PAO solutions in their operational conditions.
These solutions generate a gas type smoke and then generate gas particles that will be greater than .03 microns. The test will certify the HEPA filter is fully functioning and there is no leakage or damage.
Meaning of DOP?
DOP (Dispersed Oil Particulate) is a dispersed aerosol used to test the integrity of HEPA filters.
Meaning of PAO?
PAO (Poly Alpha Olefin) is a non-carcinogen liquid which is a most common replacement for DOP.
